What you can do
Key features
Split view
Show two open documents side by side in the same window to compare them directly, without switching tabs.
AES-256 password protection
Add or remove AES-256 encryption from your documents in a couple of clicks, right from the Protection menu. The original file is never modified.
Smooth zoom and scrolling
Navigate pages with per-tab zoom, controllable from the header bar, the status bar, or with Ctrl +/-/0 on the keyboard and the mouse wheel.
Recent documents
Quickly find recently opened files from the home screen, and remove them from the list whenever you no longer need them.
Fully offline
DocLatch requires no internet connection for any feature: opening, zooming, navigating and password-protecting documents all happen locally, with no data sent anywhere.
Light and dark theme
Switch between light and dark themes at any time from the settings. Three interface text sizes are also available.
Multilingual interface
Available in Italian, English, French and German, with the language switchable from the settings.
Compatibility
Supported formats
PDF
DocLatch currently handles PDF files only. Exporting to other formats is on the project's future roadmap.
Privacy & security
No internet. No telemetry. Ever.
DocLatch never uploads your files to any server, never sends usage data, never collects statistics, and requires no internet connection for any feature. Opening, browsing, zooming and password-protecting documents all happen entirely on your own machine.
Windows SmartScreen notice
The Windows installer isn't signed with a paid certificate yet, so it's normal for SmartScreen to show a warning on first launch. You can proceed by choosing "More info" and then "Run anyway".
